LEON CHARLES IDESOUTTER, OF LONDON, ENGLAND.

ARTIFICIAL LEG.

Application filed May 26, 1919.

To all whom it may concern:

Be it known that I, LEON CHAnLns Dn- SOUTTER, a subject of the King of Great Britain and Ireland, residing at 57 Baker street, London, in the county of London, England, have invented certain new and useful Improvements Relating to Artificlal Legs, of which the following is a specification.

This invention relates to artificial legs and refers to improved means for carrying the leg from the pelvic band, in such a way that greater freedom of movement is allowed than with the methods of carrying or suspending the artificial legs at present in use, the suspension or attachment being moreover less likely to break, become damaged or out of order than the present attachments.

And in order that my said invention may be clearly understood I will now proceed to describe the same with reference to the drawings accompanying this specification which show by way of example a typical form of fitting made according to my invention.

Figure 1 is a perspective elevation of the suspending device or attachment.

Fig. 2 is a plan view of same.

Fig. 3 is a diagrammatic and perspective view showing the device in position.

The same letters of reference are employed to denote the same parts in all the views.

(6 denotes the ordinary pelvic band, and b the strip or strap depending therefrom. c is a divided hinge at the top of the fork like device 6, cl denoting the hinge pin.

The device 6 is bifurcated or forked, its particular shape being easily understood from a comparison of Figs. 1, 2 and 8.

f are loops or eyes at the ends of the arms 0, and g are straps or the like for attaching the bucket h of the artificial leg.

It will be seen that the arms of the device are so proportioned that the artificial leg is suspended from the front and the back in such a way that the points of suspension are in a plane above the center of gravity of the limb.

This allows a free movement in the direc- Specification of Letters Patent.

tion of the arrow 70 70 in addition to the ordinary backward and forward movement around the pivot 03.

I find in practice that this method of suspension is far more efiicient and comfortable than the one generally in use.

It is to be understood that the particular construction of the suspending device may be varied while adhering to the principle of the invention as defined in the claims.

What I claim as my invention and desire to secure by Letters Patent of the United States of America is 1. In combination an artificial leg having an upper leg section adapted to fit the stump of the thigh, a pelvic band provided with a depending strap, means for suspending the artificial leg from said band comprising a bifurcated member of rigid material pivoted to said strap, the free ends of the arms of said bifurcated member being pivotally connected to the front and back of said upper leg section whereby backward and forward and sidewise movement of the leg is obtained.

2. In combination an artificial leg having an upper leg section adapted to fit the stump of the thigh, a pelvic band, a bifurcated member of rigid material comprising a shank and curved arms, said shank portion being connected to said pelvic band, said arms partially encircling the upper portion of said upper leg section and connected at their free ends to said upper leg section.

8. In combination an artificial leg having an upper leg section adapted to fit the stump of the thigh, a pelvic band, a bifurcated member of rigid material comprising a shank and curved arms, said shank being pivotally connected to said pelvic band, the free ends of said arms having eyes formed therein and flexible members secured to the front and rear of said upper leg sections and to said eyes.

In testimony whereof I afiix my signature in resence of two witnesses.
